Abstract
A lock assembly for a door includes a lock body having a housing with at least one deadbolt supported in the housing for movement between a retracted position and an extended position and biased toward the extended position by a spring, and a trigger mechanism mounted on the door separate from the lock body for engagement with a door jamb upon closure of the door, said trigger mechanism being adapted to hold the at least one deadbolt in the retracted position when the door is open in opposition to a spring bias, and to permit movement of the at least one deadbolt to the extended position upon engagement of the trigger mechanism with the doorjamb.
Claims13
A lock assembly for a door, comprising:
- a lock body having a housing;
- a first deadbolt supported in the housing for movement between a retracted position and an extended position and biased toward the extended position by a spring mounted in the housing;
- and
- a trigger mechanism mounted on the door remote from the lock body for engagement with a door jamb upon closing of the door, said trigger mechanism being adapted to hold the deadbolt in the retracted position when the door is open in opposition to a spring bias, and to permit movement of the deadbolt to the extended position upon contact of the trigger mechanism with the doorjamb.
A lock assembly, comprising:
- a lock body comprising a housing;
- first and second deadbolts supported in the housing for movement between respective retracted and extended positions and coupled for simultaneous movement between the respective retracted and extended positions and so coupled that movement of the second deadbolt from the retracted to the extended position is blocked when the first deadbolt is held in its retracted position;
- a spring mounted in the housing and biasing the first deadbolt toward its extended position;
- and
- a trigger mechanism mounted on the door remote from the lock body for engagement with a door jamb upon closure of the door, said trigger mechanism adapted to hold the second deadbolt in the retracted position in opposition to a spring bias when the door is open, and to permit movement of the second deadbolt to the extended position upon engagement of the trigger mechanism with the doorjamb.
